G. DONNELLY ASH SIFTER Filed May 8, 1929 Patented Mar. 25, 1930- GEORGEG. DONNELLY, OF'SOMERVILLE, MASSACHUSETTS ASH SIFTER I Application filedMay-8,

This invention relates to an ash shifter and has for its object toprovide a device constructed in such a manner that it may be sold andshipped in knocked-down form, thereby I be rocked through a verticalplane, the fine particles of ashes sifting through the screen of thesieve and falling uponthe main screen in the body of the device throughwhich they will fall and be deposited in an ash receptacle, while thelarger particles that do not pass through the screen of the sieve willeventually be dumped upon the main screen down which they will slide andbe discharged into a suitable receptacle. v

The invention consists in an ash sifter as set forth in the followingspecification and particularly as pointed out in the claims thereof.

Referring to the drawings: Y

Figure 1 represents a central vertical section through an ash Sifterembodyingmy in vention.

Fig. 2 is an enlarged vertical section through the top portion of thehousing of the sifter as taken on the line 2-2 of Fig. 1, portions ofthe housing being broken away to save space in the drawings.

Fig. 3 is an enlarged detail horizontal section illustrating theconstruction of one of the corners of the housing, said view being takenon the line 33 of Fig. 1.

Fig. 4 is an enlarged horizontal section taken on the line 44 of Fig. 1.

Like numerals refer to like parts throughout the several views of thedrawings.

In the drawings, 5 represents a cover for an ash receptacle, said coverbeing constructed of sheet metal and being circular in form. Mountedupon the top of the cover 5 is a housing 6, the interior of whichcommunicates with the under side of the cover 5 through an opening 7provided in the cover.

Projecting upwardly from the top portion of the cover 5 at the sides ofthe opening 7 are flanges 8 and 9, the flanges 8 being lo- 1929. SerialNo. 361,434.

cated upon opposite sides of the opening 7, and the flanges 9 also beinglocated upon op posite sides of said opening. The housing 6 embodiestherein oppositely disposed side members 10 and 11, both of which arepro- 'vided at their'lower edges with upwardly bent flanges 12 which areadapted to be interlocked with the flanges 8 of the cover 5. At theirside edges the sidemembers 10 and 11 are provided with flanges 13, seeFig. 8.

The housing 6 also embodies therein side members 14 and 15, both ofwhich have flanges 16 formed along their side edges and the flanges 16have sliding interlocking en gagement with the flanges 13 of the sidemem 'bers 10 and 11. At their bottom edges the f side members 14 and 15of the housing 6 rest upon the top of the cover 5 and contact with theouter surface of the flanges'Q, see Fig. 4. Atop member 17 ofthe housing6 has flanges 18 formed upon opposite edges thereofwhich have slidinginterlocking engagement with flanges 19 that are formed at the top ofthe side members 10 and 11. One edge of the top member 17 hasadownwardly bent flange 20 which contacts with the outer face of the sidemember 15 and the opposite edge of the top member 17 is located beneathaflange 21 which is formed at the topof the side member 14, see Fig. 2.k v Located within the housing 6 is a main screen 22 which isconstructed of open mesh wire fabric, and saidscreen is preferablyinclined at an angle of approximately 45 to the top surface of-the cover5.- A pair of rods 23 extend transversely across the housv ing betweenthe side members 14 and 15 thereof in a position to support the centralportion of the screen 22 and prevent the same from e'g n Located abovethe screen-22 and normally resting upon the upper surface thereof is asieve 24, and a portion of the frame structure 25 of the sieve isextended and pivotally mounted upon a rod 26'which is located ad'- 9jacent to the side member 10 of the housing. The side portions 27 andback portion 28 of the sieve 24 are constructed of thin sheet metal,while a screen 29 0f open mesh'wire fabric constitutes the bottom of thesieve.

A front edge 3O 01": the screen 29 is so positioned that when it isdesired to dump that portion of the material that cannot pass throughthe meshes of the screen 29, the sieve 24 may be moved to the dottedline position illustrated in Fig. 1, at which time the materialremaining in the sieve will all there from and drop on the inclinedscreen 22 down which it may slide. Thesieve 2a is rocked by means of alever 31, one end of which is secured in any suitable manner, to theframework of the sieve at a point adjacent to the top edge of the backportion 28 of said sieve, and said lever 31 extends through an openingprovided therefor in the side member 10 of the housing 6 and has ahandle portion 32 provided upon its outer portion. The lever 31 ispivotally mounted upon the rod 26.

An opening 33 is provided in the side member 10 of the housing 6 throughwhich the ashes may be inserted in filling the sieve 2i, and saidopening is normally closed by a door 34: which is pivotally attached at35 to the side member 10. An opening 36 is also provided in the sidemember 11 of the housing 6 through which the reclaimed portion 01" theashes may pass from the screen 22 down a chute 37 into a suitablereceptacle.

The general operation of the device herelnbefore specifically describedis as follows 'Assuming that the sieve 24 is resting in its normalposition on the screen 22, the door 34 is raised and the ashes areinserted through the opening 33 and deposited upon the sieve 24. Thesieve is then rocked through a vertical plane as energetically as may bedesired to cause the fine material to pass through the screen 29 fromwhich it will drop upon the screen 22, and through which it will dropthrough the chute 37.

into the ash receptacle not shown. After the fine material has allpassed through the screen 29, the sieve 24 is rocked upwardly asufficient amount to allow the residue to slide out of said sieve anddrop upon the screen 22 down which it will pass and be discharged Thedevice as a whole is so constructed that it may be sold and shipped in aknocked-down condition, thereby reducing the shipping cost and the spacerequired in packing and storing quantities of the devices. The device iseasily assembled by sliding the side members one upon another andinterlocking the various flanges one with another.

It is evident that after the side members are all secured together andto the cover 5, and the top member 17 has been slid into position uponthe side members, that the structure may be strengthened by insertingbolts through the various flanges, thereby clamping the memberstogether.

I claim:

1. An ash sitter comprising, in combination, a cover for an ashreceptacle, a housing mounted upon said cover, a screen mounted in aninclined position within said housing, and a sieve pivotally mountedwithin the housing and normally resting upon the screen.

2. An ash sitter comprising, in combination, a cover for an ashreceptacle, a housing mounted upon said cover, a screen mounted in aninclined position within said housing, and

a sieve pivotally mounted to swing through a vertical plane within thehousing above the screen.

3. An ash sitter comprising, in combination, a cover for an ashreceptacle, a housing mounted upon said cover, a screen mounted in aninclined position within said housing, a sieve pivotally mounted withinthe housing and normally resting upon the screen, and a lever to rockthe sieve.

4. An ash sitter comprising, in combination, a cover for an ashreceptacle, a housing mounted upon said cover and embodying therein aplurality of side members slidable one upon another and interlockingwith the cover, a top member slidably mounted upon the side members, ascreen mounted in an inclined position within said housing, and a sievepivotally mounted within the housing and normally resting upon thescreen.

In testimony whereof I have hereunto set my hand.

GEORGE G. DONNELLY.
